Hi,
I finally decided to make a PCB for this project, in order to be able to use the Lundahl LL1528 I have in stock, and also to use relays for some switching, to make the audio path as short as possible. Note that the input switching (phase, PAD...) are done externally. The tube sockets are ceramic that go through the PCB and are wired from the bottom. That's in order to be able to fit the PCB in a 2U rack, else the height would be excessive.
Any opinion on the routing ?
For now I have used Eagle's "polygon" function to make the ground trave as beefy as possible. Would it be a good idea to fill all blanks on the PCB with ground ?
Thanx in advance for your advices.
Best regards.
Eric
